swift 自定义上下文菜单 previewprovider 无法单击内部的任何视图使用 tapgesture

如何解决swift 自定义上下文菜单 previewprovider 无法单击内部的任何视图使用 tapgesture

我正在处理类似消息的反应，这就是我所做的（使用来自 contextMenu 的 customProvider）

下面是我向 customProvider 控制器添加表情动作时的代码

private func addReactionList(_ items : [Reaction]) -> UIView{
        let reactionView = UIView()
      
        
        var arrangedSubviews: [UIView] = []
        
        for reaction in items {
            let imgView = UIImageView(image: AppUtils.reactionToImage(reaction: reaction))
            imgView.isUserInteractionEnabled = true
            imgView.frame = CGRect(x: 0,y: 0,width: iconHeight,height: iconHeight)
            imgView.layer.cornerRadius = (imgView.frame.height) / 2
            imgView.layer.masksToBounds = true
            imgView.layer.borderColor = UIColor.clear.cgColor
            imgView.layer.borderWidth = 0
            imgView.contentMode = .scaleAspectFit
            imgView.restorationIdentifier = reaction.Type
            
            
            let tapGesture = UITapGestureRecognizer(target: self,action: #selector(handleTapGesture(_:)))
            tapGesture.delegate = self
            tapGesture.numberOfTapsrequired = 1
            tapGesture.delaystouchesBegan = true
            tapGesture.cancelstouchesInView = false
            imgView.isUserInteractionEnabled = true
            imgView.addGestureRecognizer(tapGesture)
            
            arrangedSubviews.append(imgView)
        }
        
        let stackView = UIStackView(arrangedSubviews: arrangedSubviews)
        stackView.distribution = .fillEqually
        stackView.spacing = padding
        stackView.layoutMargins = UIEdgeInsets(top: padding,left: padding,bottom: padding,right: padding)
        stackView.isLayoutMarginsRelativeArrangement = true
        
        let width = (CGFloat(items.count) * iconHeight) + (CGFloat(items.count+1) * padding)
        reactionView.frame = CGRect(x: 0,width: width,height: iconHeight + 2 * padding)
        reactionView.layer.cornerRadius = 12
        reactionView.addSubview(stackView)
        stackView.frame = reactionView.frame
        stackView.isUserInteractionEnabled = false
        reactionView.isUserInteractionEnabled = false
        
        return reactionView
    }

然后我将其添加到自定义提供程序 vc：

let actionsReacts = addReactionList(likeReactions)
        let emojiReacts = addReactionList(emojiReactions)
        if let snap = customView.snapshotView(afterScreenUpdates: true) as UIView?{
            view.addSubview(snap)
            view.addSubview(actionsReacts)
            view.addSubview(emojiReacts)
            
            let maxWidth = snap.frame.size.width >= actionsReacts.frame.size.width ? snap.frame.size.width : actionsReacts.frame.size.width
            
            var currentSnapFrame = snap.frame
            currentSnapFrame = CGRect(Int((maxWidth - snap.frame.size.width)) / 2,Int(snap.frame.size.width),Int(snap.frame.size.height))
            snap.frame = currentSnapFrame
            
            var currentActionsReactFrame = actionsReacts.frame
            currentActionsReactFrame = CGRect(0,Int(snap.frame.size.height),Int(actionsReacts.frame.size.width),Int(actionsReacts.frame.size.height))
            actionsReacts.frame = currentActionsReactFrame
            
            var currentEmojiReactFrame = actionsReacts.frame
            currentEmojiReactFrame = CGRect(0,Int(snap.frame.size.height) + Int(emojiReacts.frame.size.height),Int(emojiReacts.frame.size.width),Int(emojiReacts.frame.size.height))
            emojiReacts.frame = currentEmojiReactFrame
            
            
            preferredContentSize = CGSize(width: maxWidth,height: snap.frame.size.height + actionsReacts.frame.size.height + emojiReacts.frame.size.height)
        }

但手势无法触发，我尝试将 img 更改为按钮，但仍然无法点击

@objc func handleTapGesture(_ sender : UITapGestureRecognizer){
        let tappedImage = sender.view as! UIImageView
        let reactionType = tappedImage.restorationIdentifier ?? ""
        onSelectedReaction?(reactionType)
    }
    
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer,shouldReceive touch: UITouch) -> Bool {
        return true
    }
    
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer,shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        return true
    }

我不知道为什么我不能点击任何地方，即使我试图将手势点击添加到视图控制器视图。谁能解释一下？提前致谢

解决方法

我改用英雄动画来呈现新的VC，好无聊，但这是我现在最好的选择

我尝试根据您提供的内容重建您的演示应用程序，但我仍然不清楚您的代码是什么或其行为方式。

我注意到您正在创建 n 手势识别器并将每个识别器连接到图像视图。 尝试改用 1 个手势识别器。将其连接到您的父视图，并在点击事件上获取正在被点击的子视图。

一些代码：

 let tap = UITapGestureRecognizer(target: self,action: #selector(self.onViewTap))
 parentView.addGestureRecognizer(tap)

@objc func onViewTap(_ sender: UITapGestureRecognizer) {
    let point = sender.location(in: containerView)
    if let hitSubview = parentView.hitTest(point,with: nil) {
 // check which subview (imageView) is being hit by checking its tag or similar
}
